Modding the DW660

Just remove 4 screws (and the collet first). The rotor does not fall out, unless you pull it out. It appears that the entire shroud is not necessary unless you want to keep the spring-loaded rotor hold-down device built into the shroud. You just need to replace the 4 screws with shorter screws.

With the switch and cable housing removed. The motor part is pretty compact.
